Mongoose embedded document updating

Question

I have a problem with embedded document update.

My defined Schemas:

var Talk = new Schema({
    title: {
        type: String,
        required: true
            


        

Answer 1

When updating a Mixed type (which seems to be anything else than a basic type, so that also includes embedded documents), one has to call .markModified on the document. In this case, it would be:

talk.markModified("vote"); // mention that `talk.vote` has been modified

talk.save(function(err) {
    // ...
});

Hope this helps someone in the future since I couldn't find the answer very quickly.

Reference:

... Mongoose loses the ability to auto detect/save those changes. To "tell" Mongoose that the value of a Mixed type has changed, call the .markModified(path) method of the document passing the path to the Mixed type you just changed.
